Installers and DIYers who need a solid copper, 18 AWG two-conductor run for controls or signal wiring will appreciate the combination of a pure copper core, 300V CL3 rating and riser-rated jacket. The biggest reason to buy is predictable electrical performance for thermostat and small-signal applications coupled with UL sunlight resistance for outdoor runs.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePure Copper Conductors:\u003c\/strong\u003e Solid 18 AWG copper delivers consistent conductivity for thermostat controls, doorbells and other low-voltage signal circuits.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCMR Riser Rating:\u003c\/strong\u003e The CMR\/CL3R\/FPLR flame-retardant jacket helps meet riser installation requirements in multi-floor runs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e300V CL3 Power-Limited:\u003c\/strong\u003e Rated for 300 volts as a Class-3 power-limited circuit cable, suitable for control and signal circuits up to that rating.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSunlight Resistant:\u003c\/strong\u003e The jacket meets UL 1581 sunlight-resistance requirements, letting it be used in exposed outdoor or attic runs where UV exposure is a concern.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoHS Compliant:\u003c\/strong\u003e Meets environmental safety limits for restricted materials, useful for projects with compliance needs.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThe Syston 18\/2 cable is aimed at homeowners, HVAC technicians and electricians who need a dependable two-conductor run for thermostats, doorbells, intercoms and low-voltage control systems.
